Hm.... I got 60 Amazon EC2 cc2.8xlarge instances (don't ask, don't tell), i.e. 32x60 = 1920 cores to play with. I ran one 24 hour test with ypool.net, using rdebourbon's v3.3 for x64 Linux. It gave me about 140 XPM.
I since then switched over all instances over to beeeeer.org, using primecoin-hp 0.6 RC1 x64 for Linux. I'm around 8 hours into staring at this now:

As can be seen, not one single block found (I got around 1/hr at ypool.net), only tiny, tiny shares and not a single payout -- yet. Should I worry?
What's the problem?!
Just wait? Please give me one good reason not to switch everything back to ypool
